classification maps derived from the MBES data, can determine the habitat and
landscape features that help to explain the distribution patterns of fish in this
region.
There are some limitations to the data available from split-beam echo sounder
surveys of fish communities in coral reef ecosystems. While the split-beam
Fig. 9.12 Map of fish density on St. John Shelf, south of St. Johns, US Virgin Island. Bathymetry
is provided from hydrographic survey that included a split-beam echo sounder for fish detections.
Fish densities were calculated in 100 m segments along survey transects for two size classes:
a fish between 12 and 28 cm, and b fish greater than 28 cm
